Crédit Mutuel Arkéa suspends some operations after a cyberattack involving fraudulent transactions

Crédit Mutuel Arkéa, a regional bank of the Crédit Mutuel group based in Brittany, confirmed on Wednesday that a cyberattack had enabled fraudulent operations to be carried out, according to AFP, as reported by Euronews. The bank says its own teams detected the attack, that it is under control and that no customer will suffer losses.

To secure its operations and halt further fraudulent movements, the bank temporarily suspended some transactions and said it will resume them under optimal security conditions, according to AFP. The bank has not detailed the attackers' method.

Breton daily Le Télégramme reported that 133 million dollars had disappeared, and attributed the revelation to independent cryptocurrency investigator ZachXBT, according to AFP and Euronews. The bank has not confirmed that figure. According to journalist Grégory Raymond, cited by Le Télégramme, the funds were transferred to several accounts on cryptocurrency exchanges.

Story under review: the two pages opened reproduce the same AFP dispatch; still pending are opening the bank's statement and learning the confirmed amount defrauded, which operations are suspended and since when, and whether supervisors have been informed.
